Ubuntu Minimal 18.04 + i3-gaps

gistfile1.txt

You only need to install xorg and lightdm if you have installed Ubuntu Minimal.
If you installed a regullar Ubuntu desktop, just skip to the i3-gaps section.

xorg
====

# Xorg provides a base for a graphical environment
sudo apt install xorg

lightdm
=======

# login manager
sudo apt install lightdm

i3-gaps
=======

# Dependencies
sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf libxcb-xrm0 libxcb-xrm-dev automake

# Clone the repository
git clone https://www.github.com/Airblader/i3 .i3-gaps
cd .i3-gaps

# Compile & install
autoreconf --force --install
rm -rf build/
mkdir -p build && cd build/

# Disabling sanitizers is important for release versions!
# The prefix and sysconfdir are, obviously, dependent on the distribution.
../configure --prefix=/usr --sysconfdir=/etc --disable-sanitizers
make -j8
sudo make install

reboot
======

# now reboot your system by run this on terminal
reboot

# on login screen, click on a little button in the login box/dialog and select i3
# if you've got "failed to start session" message, click that button again and 
# select the other option and then i3 (just change to something else and back to i3)
# try to login again. If a black screen appears, just reboot your system and everything will work fine.

Oh wow, this is exactly what i'm looking for! I'm curious what the best place for the minimal install. Is that the net installer? And if so, what options are needed to be checked there. I did a mini install with the net installer and couldn't even log in after reboot
